Tired of gas engines rattling the whole block on Saturday morning? Cordless mowers have grown up: quieter starts, no fuel smells, and enough torque to handle most suburban lawns. I’ve rounded up six solid options across budgets and yard sizes, so you can match battery muscle to the grass you actually mow.
A Fast Comparison Of The Options
Greenworks 80V 21in Push Lawn Mower 4.0Ah Battery
Casince 17in Cordless Walk Behind Lawn Mower
EGO POWER+ LM2135SP Self-Propelled 21in Mower
Honda HRX217YXBEXA6 21in Battery Walk-Behind Mower
Honda HRX217YXBVKA4 21in Battery Walk-Behind Mower
Litheli 40V 16in Brushless Cordless Push Mower
The Strengths Of Each Pick
The Greenworks 80V sits in that sweet spot most weekend mowers actually want: a 21-inch steel deck that swallows wide passes, paired with an 80V brushless motor (a motor design that uses electronic magnets instead of carbon brushes, so it runs cooler and lasts longer) that feels closer to a gas unit than a toy. Run-time lands around 60 minutes on the included 4.0Ah battery, which for a typical quarter-acre lot is genuinely enough to finish in one stretch without a panic sprint to the charger.
What I like here is the single-lever height adjustment, which means no fiddling with four separate wheels when you switch from cool-season fescue to a summer Bermuda cut. Compared to the Casince below, the Greenworks trades compact storage for raw cutting width and tougher build. The trade-off is weight: it’s a push mower, so you earn every stripe.
What Stands Out
- 21-inch steel deck covers more ground per pass, meaning fewer trips back and forth on open lawn.
- Brushless motor delivers more torque (rotational force that actually turns the blade through thick grass) while staying noticeably quieter than gas.
- Single-lever height adjustment speeds up seasonal cut-height changes.
- Rapid charger refills the 4.0Ah pack in roughly an hour, handy for back-to-back sessions.
- Up to about 60 minutes of runtime covers most suburban front and back yards on one charge.
Things To Consider
- It’s a true push mower with no self-propelled assist, so flat ground is easy but sloped lots can wear you out.
- Steel deck adds weight, which makes lifting into a truck or up basement stairs a two-person job.

Who It Suits Best
Homeowners with a flat, medium-sized yard who want gas-like cutting width without engine maintenance.
Where Another Pick Suits Better
Anyone tackling noticeable slopes or thick, wet grass should consider the EGO POWER+ LM2135SP, since its self-propelled drive handles hills with far less effort.
The Casince is the kind of mower I’d point a first-time cordless shopper toward: a 17-inch deck (compact enough to snake around garden beds) and a dual 20V battery system that together push runtime up to about 40 minutes. On smaller yards, that’s plenty of headroom, and six height settings from roughly 1 to 3 inches give you real flexibility across seasons.
The honest read is that this one is built for modest lawns, not open acreage. Where the Greenworks above flexes its steel deck and 80V motor, the Casince stays lighter and friendlier to store in a tight garage or shed corner.
The Good Stuff
- Compact 17-inch deck fits through gates and stores easily against a wall.
- Two included 20V 4.0Ah batteries extend runtime up to about 40 minutes.
- Six height settings from 1 to 3 inches handle most grass types cleanly.
Honest Caveats
- The narrower deck means more passes on open lawn compared with the 21-inch picks.
- Plastic construction keeps weight down, but owners should expect lighter long-term durability than the steel-deck options.
Right Fit For
Homeowners with small to mid-size yards who want a lighter, easier-to-store cordless mower without overpaying.
Look Elsewhere When
If your lawn stretches past roughly a quarter acre or you want a self-propelled drive, the EGO POWER+ LM2135SP is a stronger match.
EGO has built a real following in the cordless world, and the LM2135SP shows why. The 56V 7.5Ah battery pushes torque up to around 7.0 ft-lbs, which is gas-comparable territory and translates to noticeably cleaner cuts through tall or damp grass. Self-propelled drive means the rear wheels actually pull the mower forward, so slopes stop being a workout.
Compared to the Greenworks above, the trade is fewer minutes per charge for a much easier push, plus a Select Cut multi-blade system that lets you swap blades for mulching, bagging, or extended runtime. The bundle includes an extra 5.0Ah battery, which is a quiet value-add for larger lots.
Bright Spots
- Self-propelled drive takes strain off slopes and long sessions.
- Select Cut system includes interchangeable blades for mulching, bagging, or extended runtime.
- 56V 7.5Ah battery plus a bonus 5.0Ah pack covers bigger yards without mid-mow swaps.
- Up to roughly 7.0 ft-lbs of torque handles thick grass that stalls weaker motors.
Points To Note
- Higher price than the push-only Greenworks or compact Casince.
- Heavier overall, so storage and transport take some planning.
Quick Facts
Made For
Homeowners with bigger yards, sloped terrain, or thick grass who want the closest cordless experience to a gas mower.
Skip It When
Shoppers with a small, flat lawn who won’t use self-propelled drive will get more value from the Litheli 40V.
Honda’s HRX line has long been the gold standard for residential cut quality, and the HRX-BE keeps that DNA in a battery package. The 4-in-1 Versamow system with Clip Director lets you toggle between mulching, bagging, discharging, and leaf shredding without swapping attachments, which sounds small until you’ve actually done it mid-mow.
Where the EGO above leans on raw torque, this Honda prioritizes refinement: microcut blade geometry (a blade design that chops clippings into finer pieces for cleaner mulching) and the brand’s reputation for engines that just keep going. The motor mirrors Honda’s GCV-series gas torque profile, so RPMs hold steady when the grass gets thick.
A Strong Showing
- 4-in-1 Versamow with Clip Director handles mulching, bagging, discharging, and leaf shredding in one deck.
- Microcut twin blade design produces finer clippings and a cleaner-looking finish.
- 21-inch deck covers wide passes in fewer rows.
Worth Noting
- Premium pricing compared to the Greenworks and Litheli options.
- Push-only drive means slopes take more effort than the EGO’s self-propelled system.
Best Suited To
Homeowners who care most about cut finish, mulching performance, and long-term durability over outright speed.
Consider Something Else When
If you want self-propelled drive for hilly terrain, the EGO POWER+ LM2135SP is the better match.
The HRX-BV variant shares the same Honda DNA as the BE above, with the same 4-in-1 Versamow system and twin-blade microcut geometry. The difference sits in the drive and bagging configuration, which tilts this version toward owners who regularly tackle tougher grass conditions or want a stronger bagging setup.
Compared to the BE sibling, this BV leans a bit more toward heavy-duty mowing routines. Same 21-inch deck, same GCV-comparable motor torque, but a bagging profile aimed at folks who collect clippings rather than mulch them back in.
Noteworthy Benefits
- Honda-grade motor torque holds RPMs through thick, demanding grass.
- 4-in-1 Versamow system switches between mulching, bagging, discharging, and leaf shredding.
- Twin-blade microcut design leaves a refined, even finish.
Room For Improvement
- Push-only format means manual effort on hills.
- Heavier price tag than mid-tier cordless options.
Who Should Grab It
Honda fans who bag clippings regularly and want the brand’s signature cut quality in a battery platform.
Reach For A Different Pick When
Owners with mostly flat lawns who rarely bag should consider the Greenworks 80V for better value.
The Litheli is the smallest footprint on this list, and that’s exactly the point. A 16-inch deck and a 40V brushless motor make this the easiest option to store in an apartment closet, a narrow shed, or behind a workbench. Two 5.0Ah batteries are required to run (both must be inserted), and the setup delivers enough runtime for a typical small suburban lot.
Six adjustable cutting heights from 25 to 75 mm give you the same seasonal flexibility as the bigger picks, and the 50L collection bag is genuinely generous for the deck size. Where the Casince above is similarly compact, the Litheli adds a brushless motor for longer life and quieter operation.
Everyday Advantages
- 16-inch deck stores easily in tight garages, sheds, or even closet corners.
- Brushless motor runs quietly and lasts longer than brushed designs.
- 50L collection bag means fewer stops to empty on small lawns.
- Six height settings from 25 to 75 mm cover most seasonal cut preferences.
Small Caveats
- Smaller deck means noticeably more passes than the 21-inch options on open lawn.
- Both batteries must be inserted to operate, which adds a small step before each mow.

Swap It Out When
Owners with a larger lawn or anyone wanting wider passes should step up to the Greenworks 80V.
What Matters Most Before Choosing Electric Cordless Lawn Mowers
Deck Size Versus Yard Size
A 21-inch deck saves serious time on open lawn, while a 16- or 17-inch model navigates tight gates and stores in small spaces. Match the deck to your lot, not your ambition, because a bigger mower in a postage-stamp yard is just awkward to push around flower beds.
Battery Voltage And Capacity
Voltage (the electrical push behind the motor) drives cutting power, while amp-hours (Ah, a measure of how long a battery can deliver that power) drive runtime. An 80V or 56V system handles thick grass the way a 20V setup simply can’t, though 40V brushless platforms like the Litheli close the gap surprisingly well for small yards.
Drive Type: Push Versus Self-Propelled
Self-propelled mowers use the motor to drive the rear wheels, which means the machine pulls itself forward while you steer. On flat lots, push models save money and storage space. On slopes or larger yards, self-propelled drive protects your back and pace, which is exactly where the EGO POWER+ LM2135SP earns its keep.
Cut Versatility
Bagging, mulching, side discharge, and leaf shredding each have a moment. Honda’s 4-in-1 Versamow system handles all of them without swapping hardware, while simpler 2-in-1 setups cost less but lock you into one style. Think about fall leaf season, not just summer grass.
Key Considerations Across These Picks
Pitfalls Shoppers Hit
Treating voltage as the only spec is a common trap: two 40V systems can perform very differently based on motor type, deck size, and battery capacity. Equally common is ignoring storage dimensions, since a 21-inch mower won’t fit in a shed already packed with a wheelbarrow. For most suburban yards, measure your gate and shed door before you measure the deck.
Where The Extra Money Goes
Higher-tier models like the EGO POWER+ LM2135SP and the Honda HRX lineup add self-propelled drive, multi-blade cutting systems, and more refined motors that hold torque under load. You may find that upgrade worth it for thick grass or sloping terrain, while flat small lots rarely benefit from the extra capability.
Frequently Asked Questions
How long does a cordless mower battery actually last?
Most modern 40V to 80V packs deliver 30 to 60 minutes per charge, though runtime varies with grass thickness, cutting height, and whether you bag or mulch. Real-world runtime often runs shorter than lab numbers in tall spring grass.
Can a cordless mower handle thick or wet grass?
Higher-voltage brushless models like the Greenworks 80V and EGO POWER+ LM2135SP handle thick grass well thanks to strong torque. Wet grass is tougher on any mower, cordless or not, and tends to clog decks faster.
Is self-propelled drive worth the extra cost?
For flat, small yards, push mowers are plenty. For slopes, large lots, or anyone with joint concerns, self-propelled drive genuinely reduces fatigue and is worth budgeting for.
How do I store a cordless mower in winter?
Remove the batteries and store them indoors at moderate room temperature, since extreme cold permanently reduces lithium-ion capacity. A quick wipe-down of the deck before storage also prevents caked grass from trapping moisture.
Are replacement batteries expensive?
Battery replacements are the main long-term cost of any cordless platform. Sticking with the same brand across tools often unlocks shared batteries, which is one quiet reason brands like EGO and Greenworks have loyal followings.
Closing Remarks
The right cordless mower mostly comes down to your lot size, slope, and how much runtime you actually need. Flat and small points toward the Litheli or Casince, mid-size lawns love the Greenworks 80V, and tougher terrain rewards the EGO or Honda builds. Match the machine to the grass you mow, and you’ll stop thinking about your mower between sessions.
